Why 3D designing
3D CAD enables you to elaborate on 2D CAD designs with three dimensional objects that allow a more accurate representation of what your team is aiming for. These orthographic projections can be built with specialist cameras and picture planes for higher quality designs.
3D design can be used to actually make things, to create things efficiently that in the past might have been difficult to create.
How does it work?
3D printing is a great way to fabricate objects because you can create objects that you couldn’t make otherwise without having complex expensive molds created or by having the objects conventionally made with multiple parts. A 3D model file can be edited by simply editing the model file. That avoids having to do any additional tooling, which can save time and money. 3D printing allows ideas to be prototype and tested without having to go through the production process. 3D solid models can be tested in different ways depending on what is needed by using simulation, mechanism design, and analysis.
Types of Modelling:
Within CAD, there are three main types of 3D modelling –
- Solid modelling works with three-dimensional shapes. The shapes may vary, but they act together like building blocks. Some of these blocks add material while others subtract, depending on the input.
- Wireframe modelling can help in cases where the surface is complex and curved. Eventually, you’ll find that the basic building blocks of solid modelling are too obtuse for some applications, and wireframe modelling provides the finesse for more complex forms.
- Surface modelling is the next step up in complexity. Highly professional applications demand smooth surfaces and seamless integration, and this can be handled by more advanced programs that require more work and computing power. However, here you can achieve shapes that would be nearly unattainable with the other two methods.
Importance of 3D design:
- Realistic, easy and quick
- Better for marketing and corrections
- Easy re-modelling and corrections
- Less cost growth
- Fewer instructions and no language barriers
- Improves drawing efficiency and accuracy
Advantages of 3D designing
3D models are used for a variety of mediums including video games, movies, architecture, illustration, engineering, and commercial advertising.
The 3D modelling process produces a digital object capable of being fully animated, making it an essential process for character animation and special effects. It allows them to not only create on-screen characters, but worlds that don’t even exist can be built.
